First though, you should hack your myBook, and play around with linux on it. you should be able to set up SSH and use ipkg to install additional software. There are Wikis and tutorials for doing that; have a look around...

Ho, ho, so I need lost of skills, to do that. For now I think this is not for me till PSMS will can stream h.2x with subtitles without transcoding it. Mybook is not a good think to do that not enough power.
